This is a lore-friendly reconstruction of Resident Evil 1 as Playerhouse with a challange for Skyrim.
Contains a completly rebuild of the Spencer Mansion, inclusive Basement, Dormitory and Laboratorium.
The whole architecture and atmosphere is close as possible to the Resident Evil game, but everything else is slightly redesigned to fit into the world and timeline of Skyrim.
The connections between all the locations are different to the original game to match the outer area good as possible and to promote the playability.
There is no listed questline, but close to Resident Evil you have to face the evil inside and solve some secrets to push through.
After the clearing the whole location is fully usable as Playerhouse, probably the biggest you can get.
(But it's not designed to be practically!)
